When deputies arrived to find Tyler Kinnon Nulisch, 30, dying from a bullet wound in his Florida Keys home, his killer and girlfriend, Brittany Nicole Holbrook, 35, claimed he had choked her. Not true, according to deputies in Monroe County, Florida. She did not have telltale marks on her throat, they said.

A court sentenced Holbrook on Friday to 40 years in prison for murder in the second degree, online records show. Authorities said she had shot Nulisch in the lower back.

“The b—- shot me in the back,” he told his roommate in his dying words.

Jurors convicted Holbrook in February for the June 17, 2023, killing.

One of Nulisch’s friends told Fox News in a June 2023 report that Holbrook acted affable — usually. Victim and killer were in love.

“Everyone saw this,” she said. “They seemed like the perfect couple.”

Holbrook, however, changed when drinking alcohol.

“She seemed so normal most of the time, but when she drank, she’d become a monster, and a switch would flip, and she’d start screaming and throwing things and hitting Tyler,” the friend said.
